Questions tagged [multiplexer]
For questions related to quantum multiplexer/demultiplexer circuits. In quantum communication, all of the system channels can be accommodated into a single channel in a larger Hilbert space. In the scheme, a single line combines the information of all the users, and, at the receiver, the original quantum channels are recovered. A multiplexer/demultiplexer circuit can perform this n qubits to qudit transformation. (arXiv:quant-ph/0701145)
